    Cyclus 1-1/8" head tube reamer/facer

    I'm going to purchase Cyclus 1-1/8" head tube reamer/facer, but they have two different sizes available and I'm not sure which one to get.
    720210 is for 33.8mm ID and 720006 is for 34mm ID. Chris King has 33.9mm ID recommendation for their 1-1/8" headsets. I measured my Chris King headset and it's 34.06mm OD, so 33.8mm reamer is definitely too tight for their recommendation, but will 34mm then be too loose?
    I'm happy with the quality of the Cyclus 44mm reamer/facer, so I'd like to get 1-1/8" reamer also from the Cyclus and they fit nicely in my budget.

    Apparently nobody knows, and neither do I, but I'd ask Peter at Ceeway since if he doesn't know he gets opinions/feedback from people that buy Cyclus tooling. I asked him about my Cyclus crown race cutter giving me issues and he was a ton of help.

    Peter is very helpful indeed, but I don't want to bother him with this as I will not purchase my tooling from him. He seems to list 720006 reamer/facer on his website, so I would guess that's what he would recommend.
